your co-founder that never sleeps

startup wisdom,
deployed at 2am.

You can code. You just don't know how to build yet.
We put 20 years of startup wisdom inside your terminal—
specific to your codebase, not a YouTube video you'll forget.

the problem

You watch the videos. You read the essays.
Then you make the mistake anyway.

2,000+
videos of startup gold
Trapped on YouTube. You can't search 2,000 videos for the 90-second clip that answers your pricing question at 2am.
Millions
of builders who can code
But can't find problems, talk to users, price products, or think about moats. They can ship features. They can't ship companies.
30 min
of mentorship per week
That's all most founders get. The advice is the same mentors have given 100 times. Mentor time doesn't scale. AI does.

seen it all before.

Real startup mentors, simulated in your terminal. They read your code. They know your stack. They don't sugarcoat.

The difference between
coding and building.

  • Finding a real problem (not a solution looking for one)
  • Talking to users (not building in a vacuum)
  • Pricing and charging (not "we'll monetize later")
  • Measuring what matters (not vanity metrics)
  • Knowing when to pivot (not sunk cost death spirals)
